  Hereinafter, a cup cleaning device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a functional diagram of a cup cleaning apparatus 100 according to the present invention. The cup cleaning device 100 includes a high-pressure water generator 50 and a main body mechanism 60. The main body mechanism 60 is composed of independent housings, and is incorporated in a confectionery manufacturing device (not shown). The high-pressure water generator 50 is installed near the main body mechanism 60. An example of a confectionery manufacturing apparatus is a tunnel steamer. The dimensions are not limited, but are about 7 m in length, about 1.3 m in height, about 1.4 m in width and use steam to produce steamed confectionery continuously. Inside the tunnel steamer, a conveyor 40 is composed of a pair of endlessly circulated chains provided in the length direction of the tunnel steamer and a plurality of elongated transport plates 41 bridged over the chain. The transport plate 41 is provided with, for example, six cups 42 in a line. In the tunnel steamer, the confectionery is manufactured when the transport plate 41 is transported on the upper surface of the conveyor 40, the transport plate is inverted by the chain, and the cup 42 is washed when the conveyor 40 returns. That is, at the time of cleaning, the opening of the cup 42 is downward.

  The high-pressure water generator 50 includes a high-pressure pump 1 and a pressure regulating valve 2. The high-pressure pump 1 is a triple-type plunger pump, which operates with a phase difference of 120 degrees and sends out pressurized water. The discharge pressure used was 1 to 10 MPa. In this example, the high-pressure water was operated at a pressure of about 7 MPa. As for the pressure, since the tap water pressure is about 0.2 to 0.4 MPa, it is understood that the pressure is higher. As shown in FIG. 1, the pressure regulating valve 2 functions to return water to the spill line when the pressure on the discharge side becomes equal to or higher than a predetermined pressure. The high-pressure water that has exited the pressure regulating valve 2 is sent to a high-pressure water hose 10. Here, the pressure gauge 6 can visually check the pressure of the high-pressure water. The hot water can be heated by using a steam pipe if steam is handled. The temperature of the hot water can be about 40 to 90 degrees, and in this example, the operation was performed at about 60 degrees.

  The main body mechanism 60 is box-shaped and has an upper opening, through which the transport plate 41 passes. Since the cup 42 faces downward, high-pressure hot water is sprayed upward from the nozzle unit 3 to perform cleaning. The nozzle unit 3 slides along the longitudinal direction of the transport plate 41, that is, in the front-back direction. A chain 5 is hung over sprocket wheels 8, 8 rotated by a motor 9 to slide the nozzle unit 3. Proximity sensors 7 are provided at both ends of the front end and the rear end. When the nozzle unit 3 comes to this position, the motor is stopped or rotated from forward rotation or stopped or rotated from reverse rotation, and the nozzle unit 3 is turned on. It slides back and forth. In this embodiment, the amount of high-pressure water is about 30 liter / minute. Further, the high-pressure water generating section 50 and the main body mechanism section 60 have separate housings, but may be formed integrally.

  FIG. 2 is a simplified perspective view showing a cleaning state of the cup 42. It is the perspective view seen from the back of the device. The transport plate 41 has an elongated shape, for example, a length in the longitudinal direction of about 1.3 m and a length in the transverse direction of about 10 cm. The cup 42 is fixed to the transport plate 41 by welding so as not to protrude from the surface of the transport plate 41. Since the cup 42 faces downward during cleaning, the hemispherical portion of the cup 42 in FIG. 2 faces upward. In FIG. 2, six cups 42 are arranged in a row in the transport plate 41, but the number is not limited to this. Side walls having a height of about 2 cm (not limited to these dimensions) are provided at both ends in the short direction of the transport plate 41. This is for keeping steam in the hemispherical portion of the cup 42 for a long time. The transport plate 41 is driven by a chain (not shown), and adjacent intervals of the transport plate 41 are separated by a predetermined interval (about 1 cm) so that the conveyor 40 can rotate at a turning point. The arrow beside the transport plate 41 indicates the return direction of the conveyor 40.

  As shown in FIG. 2, the upper part of the main body mechanism part 60 is open, the nozzle unit 3 is located at the position of the upper opening 17, and the high-pressure water of the nozzle 4 is sprayed inside the cup 42 of the transport plate 41. . The upper portions of the front end and the rear end of the main body mechanism 60 are covered with a shielding plate 21. When the nozzle unit 3 is slid to this position, the high-pressure water discharged from the nozzle 4 does not flow out to the upper part, but is blocked by the shielding plate 21 and falls to the bottom of the housing. In addition, the nozzle unit 3 is driven by a chain 5 bridged over the sprocket wheels 8, 8, and is slid in the front-back direction.

  FIG. 3 is a bottom view showing the relationship between the cup 42, the nozzle 4, and the transport plate 41. Four nozzles 4 of the nozzle unit 3 are provided, the inside of the cup 42 (one row) of the transport plate 41 is washed by the two nozzles 4 on the left side, and the adjacent transport plate is washed by the two nozzles 4 on the right side. Clean the inside of 41 cups 42 (one row). When the nozzle unit 3 slides from the front end to the rear end or from the rear end to the front end of the transport plate 41, the inner half of the plurality of cups 42 fixed to the adjacent two rows of transport plates 41, 41 in one slide. However, the surfaces of the transport plates 41 and 41 are also cleaned. Washing with high-pressure water can also remove protein stains that are usually difficult to remove with a brush or sponge.

  FIG. 4 is a front view showing the relationship between the nozzle unit 3 and the cup 42. At the time of cleaning, the gap between the transport plates 41 is closed by the lid 11. The lids 11 are provided at three places in total, so that the injected high-pressure water 12 does not flow out to the rear side of the transport plate 41. When water enters the rear side of the transport plate 41, when the conveyor 40 is turned over at the turning point, the water falls from the rear side of the transport plate 41 to the front side of the next transport plate 41, and the surface of the cup 42 is removed. Because they get dirty. The lid 11 is driven by an air cylinder (not shown) and moves up and down. Further, the conveyor 40 is operated intermittently, and the period of the intermittent operation (stop, progress) is repeated at a cycle of (6 seconds, 2 seconds). Therefore, within 6 seconds when the transport plate 41 stops, the lid 11 is lowered to close the upper part of the gap between the transport plates 41, 41, the nozzle unit 3 is slid once, and the transport plate 41 can advance again. The lid 11 is raised as described above.
